Abstract : In the continuing effort to maintain a ready force and honor the United States commitments throughout the world, in 1993 the Chief of Staff of the Army directed a test of the use of Reserve Component forces for the Multinational Force and Observers (MFO) peacekeeping mission in the Sinai. A battalion composed of 80% RC individual volunteers and 20% Active Component soldiers was activated, trained and deployed as the 28th MFO rotation to the Sinai (Jan-Jul 95). ARI conducted an assessment of personnel and training issues using performance, interview and survey data. The four research questions and their findings are as follows. (1) Personnel: who volunteered and why? what, if any, changes should be made to the volunteer screening process? (2) Family Support: How well did the family support system work? What was the impact of Sinai service on the family and civilian lives of volunteers? (3) Training/Performance: What are the unique and minimal training requirements? Did the training process produce a cohesive unit that could perform the mission? (4) Impact on the 29th ID(L): What is the impact on the ARYG units that sent volunteers, both during the deployment and post-deployment? Recommendations for future deployments are discussed in the text. ARI will continue to assess the impact of the deployment and post-redeployment re-entry on National Guard soldier commitment/retention, marital stability and financial well-being through October 1997. Cost analyses are not included in the ARI portion of the MFO assessment.
